From the following data calculate the potassium content per tablet in effervescent Kch bicarbonate tablets. Weight of 20 tablets = 35.6751 g Weight of tablet powder taken for assay = 0.1338 g The sample is dissolved in 500 ml of water and then 5 ml of the sample solution is taken and diluted to 100 ml. Weight of KCI used to prepare standard = 0.1912 g The standard was dissolved in 100 ml of water and 5 ml of the standard solution was diluted to 250 ml. The diluted standard solution was used to prepare a calibration series by transferring 0, 5, 10, 15, 20 and 25 ml to 100 ml volumetric flasks and making up to volume. The following readings were obtained for the calibration series: 0, 20.3, 40.1, 60.3, 80.1 and 100. • Reading obtained for potassium in the diluted sample solution = 73.9.
